I am sorry to hear of this. I too have a cat. the previous one i had which was a stray and befriended because she kept coming back for food. since no tags, I took care of her and gave her a place to stay even though we not supposed to have pets in apt. She was hit by a car or animal 3 yrs ago and had to put her to sleep. i just took my current cat,Mach, to the vets this morning and he has bacteria in his mouth and I have to give antiobiotics. Also, he lost weight in the past year from 12 pds to 7 and hasn't been eating much lately. they did blood work on him and wont know what itis till tues. the vet said it is something to worry about because its half his body mass and could be a disease. So i am hoping he can be treated for this. he is only 7-8. So i feel for you. Just hang in there.
